Abstract

본 발명은 입력영상신호의 주파수 레벨을 샘플링하여, 자동적으로 적정한 모니터 화면이 되도록 하는 텔레비 수상기에 관한 것이다.The present invention relates to a television receiver for sampling a frequency level of an input video signal to automatically obtain an appropriate monitor screen.

상술한 목적을 달성하기 위한 본 발명은 Y/C분리기(4)에서 분리된 휘도 신호는 통과주파수가 f1, f2, f3, …, fn으로 되어 있는 밴드패스틸터(9A)에서 주파수 스펙트럼의 검출이 행해지고, 이 검출치를 제어부(10)에 입력한다.According to the present invention for achieving the above object, the luminance signal separated by the Y / C separator 4 has a pass frequency of f1, f2, f3,... The frequency spectrum is detected by the bandpath tilter 9A, which is fn, and the detected value is input to the control unit 10.

따라서 제어부(10)는 샘플링된 검출치에 의거, 이퀄라이저(7)의 특성을 콘트롤하고, 출력되는 비디오 신호에 의해 모니터되는 화면이 보기 쉽게 되도록 한 것이다.Therefore, the control unit 10 controls the characteristics of the equalizer 7 based on the detected detection value, so that the screen monitored by the output video signal is easy to see.
